North Atlantic right whales, decimated by whaling until 1935, now face extinction. Only about 400 remain, with fewer than 100 breeding females, primarily threatened by commercial shipping and fishing.

To reverse this decline, these whales require protection from fishing gear entanglements and ship strikes. Key solutions include reducing vertical fishing lines and mandating slower ship speeds.

Bioplastics are often marketed as an eco-friendly alternative to traditional plastics. However, this "green" image can be misleading. Many bioplastics are not compostable and cause similar environmental harm, particularly in oceans, as their petroleum-based counterparts.

It's crucial to recognize that not all bioplastics offer a sustainable solution. To truly combat plastic pollution, we must move beyond all forms of plastic.
